- the amount of change due to the expansion and contraction in the lateral direction X in the first region 71 is the same as that of the second region 72.
- the first region 71 can be more easily spread in the lateral direction X and can be easily bent.
- the diaper 10 can be worn by the wearer while the first region 71 is bent as described above, the wearer's legs are not caught by the front and rear waist edges 22 and 32, and the diaper 10 is worn. Easy to earn. Moreover, since the diaper 10 can be pulled up by grasping the bent first region 71, the diaper 10 can be easily arranged at a desired position.
- the front and rear waist regions 11 and 12 extend along the front and rear end edges 42 a and 42 b of the core 42 in the second region 72. Makes it easier to bend. Since the rigidity of the second region 72 changes at the front and rear end edges 42 a and 42 b of the core 42, the first and second waist regions 11 and 12 are easily bent along the front and rear end edges 42 a and 42 b of the core 42. .
- the length dimension in the longitudinal direction Y of the front and rear waist regions 11, 12 can be substantially shortened, and the wearer's leg can be easily passed through the leg opening 16. be able to. Since the length dimension of the front-rear waist regions 11 and 12 in the longitudinal direction Y can be shortened and the diaper 10 can be pulled up, the crotch region 13 of the diaper 10 can be easily brought into close contact with the wearer's crotch.
- the front and rear waist regions 11 and 12 can be spread in the lateral direction X over the entire region. That is, not only the first and second regions 71 and 72 but also the third region 73 can be expanded. In particular, since the extension stress of the third region 73 is smaller than that of the second region 72, it tends to follow the spread of the second region 72. Further, since the gasket cuff elastic body 51 is separated from the front and rear crotch edges 23 and 33 of the front and rear waist members 20 and 30, the expansion of the third region 73 in the lateral direction X is inhibited by the gasket cuff elastic body 51. There is nothing.
- the gasket cuff elastic body 51 is attached so as to be contractible in the longitudinal direction Y.
- this contracting force acts on the third region 73, the third region 73 is difficult to expand in the lateral direction X. Such inconvenience is not caused.
- the diaper 10 is formed symmetrically with respect to the virtual horizontal center line QQ, when the seam portion 14 is formed by aligning the front and rear waist edges 22 and 32, the front and rear ends of the liquid absorbing structure 41
- the edges 41a and 41b and the front and rear end edges 42a and 42b of the core 42 can be made to coincide with each other in the lateral direction X, and these can be made annular, and the front and rear waist regions 11 and 12 can be easily bent along these.
- the third waist elastic body 83 is attached so as not to overlap the front and rear end edges 41 a and 41 b of the liquid absorbing structure 41.
- the front and rear waist regions 11 and 12 extend along the front and rear end edges 41 a and 41 b of the liquid absorbing structure 41.
- the front waist region 11 bends outward when worn, especially as it bites into the wearer's abdomen.
- the waist elastic body 83 and the front and rear end edges 41a and 41b of the liquid absorbing structure 41 from being coincident with each other, these bending at the time of wearing can be prevented.
- the present invention can be applied to a diaper that has a small length in the longitudinal direction Y of the diaper 10 and that is particularly suitable for infants. Even when the length dimension in the longitudinal direction Y of the diaper 10 is reduced, it is preferable not to make the liquid absorption structure 41 small so that the amount of absorption of urine or the like is not reduced. As a result, the ratio of the liquid absorbing structure 41 to the diaper 10 increases. In particular, in the front and rear waist regions 11 and 12, the liquid absorbing structure 41 occupies about 70 to 98% of the length dimension in the longitudinal direction Y. Become.
- the liquid absorption structure 41 generally has high rigidity, when the ratio of the liquid absorption structure 41 increases, it is difficult to spread the diaper 10 in the lateral direction X, which makes it difficult for the wearer.
- this embodiment by reducing the tensile stress of the first region 71 close to the waist opening, it can be easily spread in the lateral direction X, and can be easily given to an infant who is a wearer.
- the length dimension in the longitudinal direction Y of the diaper 10 of the present invention is about 380 to 520 mm, preferably about 400 to 450 mm, and 400 mm in this embodiment.
- the length dimension of the crotch member 40 in the longitudinal direction Y is about 350 to 450 mm, preferably about 370 to 430 mm, and in this embodiment is about 380 mm.
- the length dimension in the longitudinal direction Y of the front waist member 20 forming the front waist region 11 is about 80 to 130 mm, preferably about 85 to 125 mm, and in this embodiment, about 90 mm.
- the length direction of the longitudinal direction Y of the rear waist member 30 forming the rear waist region 12 is about 80 to 190 mm, preferably about 85 to 185 mm, and in this embodiment, about 90 mm.
- a plurality of elastic yarns are used, but not limited to this, various elastic bodies such as a band-shaped elastic body can be used. .
- various elastic bodies can be used as the gasket cuff elastic body 51 and the barrier cuff elastic body 61.
- the core 42 a core having a lateral dimension X that is smaller in length than that of the front and rear parts is used, but it is also possible to use a core having the same length in the lateral direction X. .
- the diaper 10 is symmetric with respect to the virtual lateral center line QQ, but can be used without distinction between the front and rear waist regions 11 and 12 by doing so. That is, in this embodiment, the front waist region 11 may be used so as to be located on either the abdomen side or the back side of the wearer. Therefore, it can wear without confirming the front and back of the diaper 10 in the case of wear.
- the diaper 10 is not limited to being symmetric with respect to the virtual lateral center line QQ, and may be asymmetric.
- a cover that extends further to the crotch region 13 side than the rear crotch edge 33 and covers the wearer's heel is formed. Also good.
- the first to third waist elastic bodies 81 to 83 are all attached continuously from one side edge 21, 31 to the other side edge 21, 31, but are not limited thereto.
- a configuration in which the elastic body is not attached can be used, or a configuration in which the contraction force of the elastic body is reduced or lost can be used.
- the contraction force of the waist elastic body acts intermittently in the lateral direction X
- the length A in the formula is ⁇ (the length dimension in the lateral direction X of the region where the waist elastic body is attached) / (the elongation ratio of the waist elastic body) + (the contraction force by the waist elastic body is reduced or lost)
- the front and rear waist regions 11 and 12 are partitioned into first to third regions 71 to 73, but the third region 73 is not an essential component, and at least the first and first regions having different tensile stresses. It suffices if the two regions are adjacent to each other.
- various known materials that are usually used in this type of field can be used for each constituent member of the diaper 10 without limitation.
